What it is
Microcrystalline hydroxyapatite concentrate derived from bovine bone that provides calcium in the same form found in human bones, along with phosphorus, collagen, and growth factors. Several trials show it preserves bone density better than calcium carbonate alone. More expensive than standard calcium supplements. Not suitable for vegetarians or people with bovine product concerns.
